Below, with reference to Fig. 3 (C)～(E) variation of radiator structure is described.Fig. 3 (C) is the radiator structure that only is provided with L font groove on one-sided side.Radiator structure 50A and radiator structure 50 are roughly the same, just are provided with the roughly groove 54A of L font on the side of a side.Fig. 3 (D) is smoothed manufactured radiator structure.Radiator structure 50B and radiator structure 50 are roughly the same, and just the surface is level and smooth.So far simply structure is illustrated, shows radiator structure, but the radiator structure in the reality preferably forms so smoothly with rectangular tables.
Fig. 3 (E) is the radiator structure that is made of J font groove roughly.Under the thinner situation of the irradiation diameter of laser, also can become the roughly groove of J font sometimes.In this case, the surface also is preferably smoothly and forms.The surface of radiator structure is preferably the reasons are as follows of forming smoothly.According to the illuminate condition of laser, the boundary member of cascaded surface and side becomes acute angle sometimes.When the part at the angle was in the electrode that is directly used in discharge lamp under this state, the part at angle can break away from electrode material and be devoted in the discharge space, thereby became the reason of discharge lamp melanism, caused the short life of lamp sometimes.Therefore, make the radiator structure smoothing.But when too level and smooth, the surface area of radiator structure not too increases, so be suitable value according to electrode material etc. with the power setting of laser.
Below, with reference to Fig. 4 the manufacture method of radiator structure is described.So the basic fundamental that relates to laser processing in case of necessity can be with reference to patent documentation 6,7 and non-patent literature 1,2 etc. because of known detailed.The order of utilizing laser that electrode is dug into has been shown among Fig. 4.Fig. 4 (1) is that first of expression radiator structure is made the amplification profile of example.Fig. 4 (2) is that second of expression radiator structure is made the amplification profile of example.Fig. 4 (3) is that the 3rd of expression radiator structure is made the amplification profile of example.According to Fig. 4 (1) first of radiator structure being made example describes.At first, in (A), columned electrode is pivoted, simultaneously the electrode irradiating laser is dug into the roughly groove of V font.Next, from (B) to (E) be irradiating laser equally, is dug into the groove of a plurality of roughly L fonts on the inclined-plane of the groove that utilizes (A) to produce.Here, be not limited to the order that is dug into other grooves on the inclined-plane of the groove that utilization (A) produces especially from (B) to (E).In addition, about situation that form to utilize the groove that (A) produce and the situation that is dug into other grooves, be preferably the suitably output characteristic of setting laser.
For example, when utilizing (A) to be dug into V font groove, the perpendicular laser of main surface of irradiation and electrode, when from (B) to (E) was dug into other L font grooves, the inclined-plane of best and V font groove is irradiating laser perpendicularly.In addition, when utilizing (A) to be dug into V font groove, can widen the irradiation diameter of laser, but when from (B) to (E) is dug into other L font grooves, preferably reduce the irradiation diameter of laser.Smoothing is meant while making electrode make laser continuously along the moving axially of electrode around the rotation of columned central shaft, thereby makes the surface of the radiator structure of electrode become level and smooth.In addition, also can realize smoothing by the high-temperature heat treatment in electrobrightening or the vacuum.
According to Fig. 4 (2) the second making example of utilizing laser to make radiator structure is described.In (A), Yi Bian columned electrode is pivoted,, make the axial dipole field of laser then along electrode Yi Bian the electrode irradiating laser is dug into groove, further shown in from (B) to (E), be dug into groove like that.In this embodiment, be laser to be moved vertically by stages shine, but also can be by while columned electrode is pivoted to electrode irradiating laser and the irradiation position that makes laser along axially the moving continuously of electrode, thereby form the radiator structure of level and smooth step type slot.
According to Fig. 4 (3) the 3rd of radiator structure being made example describes.Utilize laser to be dug into out after the large diameter groove in (A), utilize laser to be dug into the groove of middle diameter in (B), the groove that utilizes laser to be dug into minor diameter in (C) is made.In the present embodiment, the irradiation diameter that from big to small changes laser by stages is dug into out groove, but also can change the irradiation diameter of laser by stages from small to large.Also can be by while columned electrode be pivoted to the electrode irradiating laser, and change the irradiation diameter of laser continuously, thus form the radiator structure of level and smooth step type slot.Utilize above method to make radiator structure.
Put down in writing in the present embodiment along the radiator structure of the circumferencial direction of electrode, but same radiator structure also can along electrode axially.In addition, for example understand anode, if but on the main part of negative electrode, radiator structure is set, also can obtain same effect.
As mentioned above, in an embodiment of the present invention, discharge lamp constitutes and uses the anode with such radiator structure: this radiator structure is made of a plurality of parallel endless grooves, the cross section of this endless groove is the V font and has two rank or the side of the step type slot on three rank, so can in the intensity of the radiator structure that keeps electrode, improve radiating effect, can prolong the life-span of discharge lamp.
